T 0 all whom it may concern:

Be it known that l, JOHN ILLINGWORTH, a citizen of the United States, residing at Newark, in the county of Essex and Stateof New Jersey, have invented certain- Improvements in lngot-Oompressing Apparatus, of which the following is a specification.

This invention relates to the art of casting ingots as illustrated by my prior patents No, 594,157 of November 23, 1897, No. 644,918 of March 6, 1900, and No. 810,654 of Jan uary 23, 1906, and the present application is a division of my earlier one filed June 28, 1906, Serial No. 323,822.

The objects of the invention are to enable the ingot to be compressed directly, or without the intervention of the mold, for the removal or prevention of piping; to thus eliminate .the strain and wear upon the molds, as Well as their liability to breakage under the severe pressure; to thus reduce expense; to enable either a sectional or solid mold to be employed in connection with compression of the ingots; to secure effective pressure of the ingot and thus obtain a solid and perfect ingot, and to obtain other advantages and results as may be brought out in the following description.

Referring to the accompanying drawings, in which like numerals of reference indicate corresponding parts in each of the several figures, Figure 1 is a plan of a machine of my improved construction; Fig. 2 is a ver tical cross-sectional view on line Y Y, Fig. 1, and Fig. 3 is a vertical face view of a certain sliding mold with two ingots therein.

It will be understood that heretofore in the art, as shown by my prior patents, the ingot has been compressed while still in its mold, and to this end the mold has been made sectional with filler pieces to be removed, or wedges to be inserted in a solid mold, and so both mold and ingot have received the pressure together. As a result, the molds have been liable to be broken or damaged, and inasmuch as the construction -of said molds involves much labor and expense, their breakage is a considerable item. By my present improved method herein set forth, the ingot is removed from its mold While yet partially soft and subjected to pressure directly and alone, without the mold.

In carrying out this method, after the molten metal has been poured in any ordinary and Well-known manner, the ingot is allowed to cool slightly so as to solidify at its outer portions next the mold and is then removed from said mold either by its natural shrinkage or by the use of a strip )er or in any other suitable manner. After t iis removal, and while the central portion of the ingot is still soft, it is subjected to compression preferably at its lateral surfaces, by any suitable pressure-exerting means, one of which will be hereinafter described.

In the drawings 1 indicates a sliding false mold adapted to be reciprocated in vertical position upon a bed-plate 2, by means of hydraulic cylinders 3 having their pistons 4, connected thereto. This false mold has at one lateral face of itself a series of vertical pockets or seats 5, each adapted to receive an ingot as 6, so that the same is held upright and carried along the bed-plate. At one side of the path of this false mold l is a back-plate 7 which is fixed and engages the rear or smooth face of the mold to provide a firm support therefor.

At the opposite side of the path of the sliding mold from the said back-plate is a ram 8 operated by means of hydraulic cylinders 9 and adapted to be forced toward the back plate 7 to compress each ingot in the false mold as it comes in line with the said ram. Only one ingot is thus compressed at a time, but while this is being done another ingot is being inserted in the sliding mold on one side, while on the other a compressed ingot may be taken out as soon as it has cooled and shrunk sufficiently. Any number of seats or pockets may be provided in the sliding false mold, but preferably enough so that its operation may be carried on as just above stated. Tie rods l0, 10 serve to connect the back-plate 7 rigidly to the cylinders 9, and secure great i'irmness and solidity.

The construction thus described is adapted for use with good advantage on small ingots of a few hundred pounds or so, where pressure from two opposite sides is suilicient to close the piping or cavity of the ingot.

Any suitable pressure exerting means could be used instead of the hydraulic cylinders and pistons shown, and operated by any available power means; the term ram is therefore to be understood in such a broad sense. Furthermore, any suitable backing might be provided for the false mold to resist the pressure on the ingots.

Other modifications and changes could be made from the construction specifically shown and described Without departing from the spirit and scope of the invention, and do not Wish to be understood as limiting myself by any positive descriptive terms herein employed except as the state of the art may require.

Having thus described the invention what I claim as new is:

l. The combination With reciprocating pressure exerting means, of a sliding false mold adapted to reciprocate across the path of said pressure exerting means and having at its face next said pressure-exerting means a seat for an ingot, and means for supporting said false mold against the strain of said pressure-exerting means.

2. The combination with a reciprocatory ram, of a sliding false mold adapted to reciprocate across the path of said ram, said false mold having at its face next the ram a seat for an ingot, and a rigid back-plate for said false mold.

3. The combination With reciprocatory pressure-exerting means, of a sliding false mold having in its lateral face a vertical ingot recess, and means for sliding said mold to bring an ingot in the recess thereof into the path of said pressure-exerting means.

4. The combination With pressure-exerting means, of a false mold having in its face an ingot seat, one of said parts being movable With respect to the other, and means for bringing the said ingot seat into the path of said pressure-exerting means.

5. The combination with a reciprocatory ram, of a sliding false mold adapted to be reciprocated across the path of the ram and having at its face adjacent thereto a plurality of ingot seats or pockets, and a back-plate for said false mold.

. Ingot compressing apparatus, comprising in combination a bed-plate, a reciprocatory false mold having vertical transverse recesses for ingots opening at their lower ends against said bed plate, and reciprocatory pressureexerting means adapted to operate transversely of the path of said mold.

7. lngot compressing apparatus, com rising in combination a slidable false mold aving in its face a series of ingot seats, reciprocatory pressure-exerting means adapted to act on each ingot as it is brought into place by said false mold, and means for sliding and for supporting said false mold.

8. The combinationavith ya reciprocatory ram, a back-plate opposite said ram, cylinders and pistons for operating the ram and tie rods connecting said cylinders and back plate, of a sliding false mold adapted to pass between said back-plate and ram and having in its lateral face next the ram a series of seats or pockets for ingots, said series being of vgreater length than the Width of the backplate and ram, whereby some project While others are in use.

9. In an ingot compressing apparatus, the

combination of a member having an ingot seat adapted to inclose an ingot at three of its lateral surfaces and expose the fourth, means engaging one end of said ingot While in said seat, and pressure exerting means adapted to engage the said exposed fourth side of the ingot.

10. The combination With reciprocatory pressure exerting means, and a support therefor, of a movable false mold having in its face next said pressure-exerting means a series of seats or pockets for ingots, said series being of greater length than the Width of the pressure-exerting means, whereby some project While others are in use.
